Canister Proportional Purge Solenoid Valve

This example of a pulse width modulated, proportional flow control solenoid valve is used in a vehicle's emission control system.

This pulse width modulated (PWM), proportional flow control valve is part of the emission control system in a vehicle. As the vapors from the vehicle's fuel system are stored in a charcoal canister, the solenoid valve proportionally regulates the flow and amount of fuel vapor from the canister back into the combustion process.

PWM and Emissions Control

Our engineers helped devise a canister proportional purge solenoid valve that applies pulse width modulation (PWM) to emissions control system in a vehicle.

Our engineers begin by designing with 3D CAD and performing electromagnetic and fluid dynamic analysis with state-of-the-art finite element analysis software. Every design is engineered and tested in our lab to meet our customers’ specifications.

Increased Performance

Precise control with high accuracy through tighter tolerances. Reducing friction and inefficiencies provides extremely low hysteresis.

Lighter Weight

Multiple variables in the design and manufacturing process are optimized to reduce overall weight and size of the solenoid or valve.

Minimized Footprint

Custom solenoids can be designed to utilize the best control scheme for your application, resulting in a minimized footprint.

Limited Power Consumption

Latching technology in solenoid and valve design minimizes overall power consumption.

Extreme Environments

Can be designed to meet extreme environments that include moisture, dirt/dust, vibration and/or extreme temperature requirements.

Built-in Safety

Failsafe modes are designed into solenoids and valves utilizing integrated electronic controls.
